CARBURETER.

SPECIFICATION forming part of Letters Patent No. 688,8 i4, dated December 17,- 1901.

Application iiled April l, 1901. Serial No. 53,853. (No model.)

To all whom t may concern:

Be it known that I, OLIr` ANDREsoN, a citi- 'Zen of the United States, residing at Elgin, in the county of Kane and State of Illinois, have invented a new and useful Apparatus for Oarbureting Air, of which the followingis a speciication.

My invention is an improved apparatus for earbureting air by mixing the same with the vapor of gasolene or other liquid hydrocarbon; and it consists in the peculiar construction and combination ot' devices hereinafter fully set forth and claimed.

In `the accompanying drawings, Figure l is a vertical central sectional view of a carbureting apparatus constructed in accordance With my invention. Fig. 2 is partly a top plan view of the same and partly a section taken on a plane indicated by the line a a of Fig. l. Fig. 3 is a vertical central sectional view of a modified form of my invention.

The tank or chamber l is kept supplied with a suitable quantity ot' gasolene or other liquid hydrocarbon. As here shown, the gasolene is fed to the tank l from a reservoir 2 by a tube 3, which communicates with tank l'near the lower side thereof.

Within the chamber l is a carburetingchamber 4. The same comprises a lower head 5, an upper head 6, and a webV 7, which The lower head is perforated, as at S, and is provided with a depending flange 9. The web 7 is made of cloth or other suitable absorbent material through which air can pass. The lower head 5 is entirely submerged in the gasolene in the tank l and the lower portion of the absorbent web 7 is also submerged therein. An air-inlet pipe l0 passes downward through an opening in the top of the tank l and through central openings in the lower and upper heads. The latter are secured to and supported by the said inlet-pipe 10. The lower submerged end of the latter is open, as shown. An outlet-pipe ll leads from the top of the tank l.

In the operation of my improved apparatus the air passes downward through the pipe l0 and is forced through the body of gasolene in the lower portion of tank l. The air is confined under the head 5 by the iiange 9 thereof and rises through the body of gasolene,` passing through the openings 8 in said lower head into the carbureting-chamber 4 and passes through the absorbent web 7 of the latter. This absorbent web being kept saturated with the liquid hydrocarbon by capillary action, the air is the more effectually carbureted as it passes through the said web. The carbureted air or gas passes from the tank l through the pipe 1l. The tank l is provided with a suitable gage, as at l2, 'by means of which the quantity of gasolene therein may be readily ascertained. I employ a spreader 13, which is here shown as a circular disk disposed at a suitable distance below the intake end of the pipe ll. The spreader forms a battle between the said pipe and the nearest portion ot' the carburet-ing chamber and serves to thoroughly commingle the vapors as the same rise from the carbureting-chamber.

In the modified form of my invention (shown in Fig. 3) I employ a plurality ot' the carbureting-chambers 7. The same are suspended from a diaphragm Ct in the tank l by the pipes 10a. The said pipes communicate with the air-space b between said diaphragm and the top of the tank. The air-inlet pipe l0 communicates with the air -space b. The air passes downward from the space b through the pipes l0a into the body of gasolene, rises through the latter and the openings 8 in the lower head 5, becoming thereby carbureted, and passes through the absorbent webs of the carbureting-chamber 7, as before. In this form of my invention a spreader c is interposed between the air-inlet pipe l0 and the proximate pipes 10a, hence causing an equal volume of air to pass downward through each of the pipes l0a and distributing the work equally to each of the carburetingchambers.

It will be observed by reference to the drawings that the tank or reservoir 2 is at such an elevation that the gasolene is maintained at all times at the required level in the tank l and that the gasoleneis fed to the said tank as the same is consumed therein.

Having thus described my invention, I claiml. In a carbureter, the combination of an inclosing tank, a carbu retin g-ehamber 'theren in, the latter comprising an upper head, a

lower head and an absorbent web connecting said heads, and forming the inclosing wall of said carbureting-chamber, the lower portion of said carbureting-chamber being submerged in liquid hydrocarbon, an air-inlet pipe discharging under said lower, head and a gas-pipe leading from the gas-space of said tank, substantially as described.

2. In a carbureter, a carbureting-chamber comprising an imperforate upper head, a perforated lower head having a depending ilange, an absorbent web connecting said upper and lower heads, andv forming the inclosing wall of said carbureting-chamber, and means to force air through a body of liquid hydrocarbon into said chamber and from the interior of the latte/r outward through the absorbent web forming the inclosing Wall thereof, -substantially as described.

3. Ina carbureter, the combination of a vertical tube, an upper, imperforate head se- OLIF ANDRESON.
